It seems like you want to download a pre-existing piece of Japanese text in picture form. I think it would take a while to trawl through the net trying to find a jpeg of those particular kanji. However, it's not particularly hard for those of us who do have Japanese enabled on our machines to make Japanese text into a picture file for you.

If you email me, I'll send you a pdf or whatever you like of the kanji in a few different brush fonts.
